METHOD OF PRODUCING BOXES OR SHIPPING CASES FROM MULTIPLY VENEERED PANELS.

Application filed March 9, 1926. Serial No. 93,406.

This invention pertains to an improyed method of producing boxes or shipping cases from multi-ply glued veneered wood panels.

The method employed at present 1n the construction of boxes and crates from veneered material is both expensive and wasteful. embracing, as it does, the use of severalseparate and distinct sheets 1n the 1 formation of their bottoms. sides, ends and tops. these being braced and cleated together at their joined edges to supply the necessarv rigidity and strength and adding materially to the weight, as well as the cost. As

contemplated in my improved method, the bottom and sides, or the bottom. sldes and ends. as the case may be. of the box are formed from a single sheet of veneered panel. thereafter assemblage being a matter of simple and easy accomplishment.

A primary object of the present invention is the provision of improved means and method of producing boxes and cases of the character referred to from glued veneered i wood panels formed and prepared as described in mv co-pending application, Serial No. 90.027. filed Februarv 23. 1926.

A further obiect of the invention is the production of boxes and cases of the chara'cter-desionated. by forming them up from the Hat glued veneered panel immediately, subseoucnt to the steaming operation undergone by the panel. employing for the purpose a forming. or shaping. block.

the rovision of a shi ping box. or case. that is cheap as to construction. and light and durable without sacrifice 0 strength. and one that may be constructed from a single blank.

An embodiment of mv invention is shown in the accompanviuri'rldrawings, forming a part of this specification and in which similar .characte s of r ference rater to lik parts throughout t Fimire 1 is a perspective view of a box formed. atter m method. from a panel of pre-Ferablv two-ply g ed wood material. the bottom and s des o ly being formed from F v ne r. the ends. in th s construction. being f m'rlinar unvenee ed material:

Figure 2- is a diagrammatic end view showing the method of shaping the steamed Still another obiect of the invention is glued veneered wood panel about a forming block by the aid of shaping straps;

Figure 3 is a diagrammatic view of a blank as cut from a glued veneered wood panel in readiness for shaping up into the sides and ends of a box by means of a forming block aided by straps, as described;

Figure 4 is a perspective View of a completed box and cover, after the ends have been riveted or stapled and the cover in place;

Figure 5 is a perspective view of another form, in which the sides and ends are formed from one piece of glued veneered wood material, overlapped and riveted at one side, the bottom and cover being made separately and inserted in place;

Figure 6 is an end view, partly in section of the construction shown in Figure 5, and is illustrative of the method of securing the bottom and cover sections in place; and

Figure 7 is a detail view of a portion of the blank from which bottom and cover are formed.

The process of making the glued veneered wood material from which the boxes, or cases, are constructed is substantially that described in my co-pending application, previously herein mentioned, and is as folows:

First-The veneering is turned. from the boiled or steamed log as a continuous unseasoned sheet. by means of a veneer lathe;

Second-The sheet thus obtained is cut into sections of equal length by a specially designed rotary cutter;

Third.-The sections, preferably in pairs, are run through a glue-spreader, giving to the outside surfaces a coating of waterproof glue, after which there is added to each of the glue-covered surfaces an unglued section. thus forming two two-ply glued veneer wood sections; and

Fourth-Carrying under pressure the 1lti-p1y sections thus formed into and through an extended artificially heated drying kiln between pressure-regulated continuously moving conveyors and discharging these multi-ply constituted sections as seasoned veneer sheets.

The method of and means for forming a glued veneered wood multi-ply panel has been fully set forth and described in my copending application hereinbefore referred to, and it is to the veneered material thus produced that the herein described method particularly pertains. In constructing boxes and cases from the material specified, the blanks, after steaming, and while still hot and pliable, are forced to conform to the con-- figuration of a selected design. In illustration, in forming up the several designs for boxes and more particularly that shown in Figure 1, a block-form 10 of the desired configuration is employed, about which the steamed blank 11 is shaped with the aid of the straps 12. the glued veneered wood panel 11. being placed between the block 10 and the straps 12 and the force necessary to compel the blank to take the required form applied to these straps, bending them and thus forming the bottom 13, and, likewise, sides 14 and 15, between which unveneered end pieces are secured by nailing.

In forming theblank 18 into a box, as shown in Figure 3, the blank is first slit in two places from opposite ends, as indicated at 19, 20, 21 and 22, and thereafter steamed, after which the sides and ends are formed up about a block by means of straps, after the manner described in connection with the construction shown in Figures 1 and 2. the overlapped ends being then riveted, or stapled, as indicated at 23, in Figure 4:, to complete the box.

In Figures 5 and 6, a box is shown as constructed from a multi-ply veneered glued wood blank 24, bent to form the sides 25 and 26, and the ends 27 and 28, with the overlapped, ends 29 and 30 of the blank riveted, or stapled, as indicated at 31, after which a flanged bottom 32, also formed of a like multi-ply veneered glued wood blank and bearing a flanged edge 33, is inserted in the body thus formed and riveted, or stapled,

ealace placed upon the blank and the marginal edges 37 bent to form flanges to accommodate the rivets, or staples.

Having thus described my'invention, I

claim, and desire to secureby Letters Patent:

1. The method of producing a veneered receptacle, which consists of, first, producing a. blank of waterproof-glued veneered wood multi-ply material and slitting the same to permit forming the bottom, sides and ends of the receptacle, then steaming said blank to render it pliable, next placing said steamed blank upon a form with metal straps thereabout and bending straps and blank together about said form, with ends in overlapped relation, and, thereafter, removing said form and straps from the shaped blank and securing said overlapped ends together.

2. The method of producing a veneered receptacle, which consists of, first, producing a blank of waterproof glued seasoned multiply material and slitting the same to form bottom, sides and ends of the receptacle, then steaming the blank to render it pliable, then placing said steamed blank, with metal straps thereabout, upon a form and bending said straps and blank to conform to the shape of said form to produce the said bottom, sides and ends, then removing said form and straps from the shaped blank, and, finally, riveting, or stapling, the ends in overlapped relation.

In testlmony whereof I have affixed my signature.

HENRY V. POINTER.
